Overview

CVE-2026-23426 is a medium-severity vulnerability. It was published on April 3, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm/logicvc: Fix device node reference leak in logicvc_drm_config_parse()

The logicvc_drm_config_parse() function calls of_get_child_by_name() to

find the "layers" node but fails to release the reference, leading to a

device node reference leak.

Fix this by using the __free(device_node) cleanup attribute to automatic

release the reference when the variable goes out of scope.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
